I ran out of time before I was able to do Alot of tuning on the car do to weather here in Michigan. But I've been doing some garage tuning with my wideband and ill be ready for when the weather breaks. I've also been fighting old fuel issues. And I'm actually in the process of installing a fuel cell and some upgrades to my fuel pump.
But to answer your question yes the car has seen as much as 18 psi of boost by mistake it totally caught me off guard. But I've ran a couple first thru third pulls at 8 psi with rock solid afr's.
